Hello! I have been coming to the forums for help and advice but have never posted my own. But my bettas face looks sick and I'm not sure what it is. Please help! The blotches appeared and disappeared off and on since I got him in august. I'm not sure what I should try. Maracyn-two didn't work and neither did aquarium salt. I tried bettafix and melafix too but they didn't do anything. Bhe

He is still eating. He's his usual grumpy and adorable self, he acts and swims fine. he just looks....weird. I know that bettas change colors throughout their lives but it doesn't really look like that.

Generally you only need to worry when you see behavior changes or more than one physical symptom. My Betta is turning brown and has lighter colored places on his face like yours. He has had them for weeks and is still fine. Their appearance can change randomly for no apparent reason, but it's not really something to worry about if no other symptoms are present, IMO.
